Actor Alyssa Milano took to Twitter on Sunday with an idea, suggested by a friend, she said.

She urged any women who have been sexually harassed or assaulted to write two words on Twitter: “Me too.”

“If all the women who have been sexually harassed or assaulted wrote ‘Me too’ as a status, we might give people a sense of the magnitude of the problem,” wrote the actor, who is known for her roles in “Who’s the Boss?,” “Melrose Place” and “Charmed,” and as a host on “Project Runway All Stars.”

Milano starred in “Charmed” alongside Rose McGowan, one of film producer Harvey Weinstein’s accusers. She is also friends with Weinstein’s wife, Georgina Chapman, and wrote in a blog post that she was sickened by the “disturbing” sexual abuse allegations against him.

Women listened. Within hours, tweets with the words “me too” began appearing in droves. By 4 a.m. Monday, more than 200,000 #metoo tweets were published by Twitter’s count. The stories came pouring forth on Facebook as well with nearly 80,000 people said to be “talking about this” by the wee hours Monday.
